In order to know the present or to predict the future, one needs to be well acquainted with the history of the specific context, and the history of the allied contexts. Considering any academic field, history of evolution of that subject, plays an important role in building the theoretical foundation. However, going through the history can sometimes prove out to be very biased in nature, as the historical events can be categorized into two parts, documented and undocumented. The history referred so far, is the documented history, but what about the undocumented history? This part may sound critical and debatable. It may be possible that, with the graduation of time, many historical documents are lost or being faced with deterioration. However, many historical events are not documented with some specific intentions, may it be personal, political, or economical. In order to depict the whereabouts of that particular undocumented period, some manipulated or stylized facts are published, so that the real incidents can lie hidden in the darkness. Therefore, analyzing historical vents always needs to be verified from multiple sources, and it is required to note down the contradictions noted in those documents.
